Key Facts

The Sentinel-2B satellite is part of satellites system that monitors Earth. It will join its twin Sentinel-2A, which has been in orbit since 2015. The two satellites will orbit 786 km above Earth, on opposite sides of planet.

They will take high-resolution, colour and infrared images for a wide array of environmental initiatives, including crop forecasting and monitoring natural disasters.

Together, they will cover all of Earth’s land surfaces, large islands, inland and coastal waterways every five days, providing more up-to-date images and at higher resolution than have been available.

It will help track pollution of lakes and coastal waters, monitor land changes and produce disaster maps by providing information on floods, landslide and volcanic eruptions.
